Vietnamese American Anti-Imperialism: South Vietnamese History And Analysis Of Publications Pre-1975, Jeannie Nguyen

Master's Theses

During the Vietnam War, citizens contested US imperialism at multiple levels. In South Vietnam, citizens published newspapers and magazines to challenge their government and expose the depth of US aggression in South Vietnamese society and culture. Inside the imperial core, Black, Chicano, and Asian American activists formed solidarities to resist the war and challenge racial inequality. At the intersection of imperialism inside and outside its borders, lies a group of South Vietnamese students and scholars who became American, migrating during the war via state-structured projects. However, in response to the heightening of war and drawing inspiration from their ‘Third World’ …

Sleeves were manufactured to rotor design specifications (50-mm width, 1.2-mm thickness, 88.6-mm diameter) and tested per ASTM D2290 Procedure A to determine apparent hoop-failure stress. These experimental results validated a finite element model of the D2290 test, confirming realistic strain patterns …

Delayed Timing Of Spring Application Of Nitrogen In Corn, Elizabeth Mae Worley

Theses and Dissertations

Application timing of nitrogen (N) fertilizer within the corn growing season can be crucial to crop nutrient uptake and availability. A lack of region-specific timing recommendations may result in inefficient fertilizer use and inconsistent yield responses. The objectives of this study were to determine how late in the growing season a first and second N fertilizer application can be pushed until corn yield is impacted and investigate whether Growing Degree Days (GDDs) should be used as better estimate of timing for N application than calendar date or growth stage. First applications were able to be delayed until V4-V6 growth stages …

Beyond English: Auditing And Mitigating Cross-Lingual Data Contamination In Multimodal Large Language Models, Pavan Dharma Adapa

Theses and Dissertations

This thesis extends data contamination auditing for multimodal large language models to multilingual settings. Using LLaVA 1.5 and a high-fidelity French parallel dataset derived from ScienceQA, the study evaluates how performance changes when identical image-question pairs are translated from English to French. The resultsshow a substantial cross-lingual performance decline and frequent flips from correct English predictions to incorrect French predictions, indicating that benchmark performance can depend heavily on memorized English-specific patterns rather than stable multimodal reasoning. To address this weakness, the thesis introduces an inference-time mitigation strategy based on perturbation ensembling and cross-lingual consistency aggregation. The proposed method reduces instance-level …

Faculty Perceptions Of Transfer Students: How Characteristics And Experiences Inform Faculty Predispositions Toward Transfer Students In Senior Institutions, Tracey Ann Dubard

Theses and Dissertations

Faculty perceptions of student populations have been widely discussed, but the conversation has seldom focused on the transfer student population. Because a third of community college students choose to transfer into four-year institutions, the elements of the environment awaiting them are worthy of exploration. The classroom setting is a shared experience for transfer students. Therefore, faculty can play a significant role in creating a climate of support for this population. However, the opposite may be true. Transfer students often arrive on campus to find an environment that is mostly focused on traditional students. The lack of a supportive environment may …

Rethinking Social Disorganization In Rural America: Persistent Poverty, Institutional Fragility, And Crime, Addison Finch

Theses and Dissertations

Social Disorganization Theory (SDT) links structural disadvantage to crime through mechanisms such as residential instability, weakened social networks, and reduced informal social control in urban neighborhoods. Less is known about whether these mechanisms operate similarly in persistently poor rural communities where disadvantage is enduring rather than destabilizing. This study examines whether variation in poverty intensity predicts county-level crime in nonmetropolitan, persistently poor counties in Kentucky and Tennessee from 2016 to 2023. A balanced county-year panel (N = 344) integrates incident-based crime data with measures of poverty intensity and institutional capacity. Pooled ordinary least squares models with year fixed effects and …

A Pedagogically Effective Conceptual Framework For The Resilience Of Unit Test Suites To Refactoring, Daniel Paul Knight

Theses and Dissertations

Unit test suites are intended to support safe and efficient source code refactoring, yet in practice they can hinder rather than help when tests are tightly coupled to implementation details. Such non-resilient tests require frequent co-evolution, consume valuable engineering time, and may disincentivize beneficial code improvements. While concepts such as passive and active resilience, test smells, and technical debt have been studied individually, they have not been integrated into a single actionable framework, nor has their pedagogical value been systematically evaluated. This dissertation introduces a novel conceptual framework for the resilience of unit test suites to refactoring, grounded in resilience …

Harmonic Response Analysis Of Asymmetric Double-Wishbone Suspension Systems For Amphibious Vehicle Stability, Harper K. Mccraw

Theses and Dissertations

Amphibious vehicles in the surf zone face severe hydrodynamic forcing, yet their internal suspension dynamics remain under-characterized. This research quantifies the non-linear dynamic response of an asymmetric double-wishbone suspension under regular wave impact. Using a physical model in a wave flume and a Qualisys motion-capture system, global rigid-body roll angles were processed through a decoupled kinematic numerical framework to isolate time-domain strut displacements. To evaluate stability, the data was transformed into the frequency domain to calculate Total Harmonic Distortion (THD). Results indicate that all test configurations exhibited significant non-linearity, primarily driven by mechanical clipping as struts reached their physical travel …

Unbounded Derivations On Algebras Associated With Monothetic Groups: An Expository Thesis, Britton Phillips

Theses and Dissertations

This thesis is an expository exploration of the paper Unbounded Derivations in Algebras Associated with Monothetic Groups. Monothetic groups will be utilized to create a minimal system that gives rise to two C*-algebras, and once we have these algebras, unbounded derivations will be able to be defined on them. These derivations are able to be classified and decomposed into ”special” derivations, and these decompositions help simplify the comparisons between derivations on different algebras. In particular, we emphasize the classification, covariance properties, innerness and approximate innerness, and the lifting behavior of these derivations.

In The Pursuit Of Beauty: A Bureaucratic History Of Chicago's Parks, 1860-1900, Jackie L. Perkins

Theses and Dissertations

This dissertation examines how the decentralized and competitive urban government of Chicago regulated not only the material conditions but also the aesthetic beauty of three separate park systems formed in 1869 as a response to Chicagoans’ broad push for improved recreational landscapes in the city. The systems, political entities each governed by its own commission, experienced varying levels of independence from the city of Chicago. As commissioners worked towards the creation of urban parks modeled after the idealized beauty made popular by New York’s Central Park, they encountered the bureaucratic and environmental realities of Chicago, two forces that often worked …
